When necessary, users can manually adjust the camera's focus and 
zoom. Connect the camera’s BNC connector to the video input of 
a monitor to aid you in lens adjustment. Then refer to the steps 
below.
1. Loosen the top screws to separate the camera's sunshield from 

the housing.

2.  Remove the lens cover at the front by turning it 

counterclockwise. Then turn the zoom ring on knob 1, and the 
focus ring on knob 2. When complete, re-install the lens cover.

Note:

 Users may open up the front cover of the bullet camera 

series for focus & zoom adjustment. Care must be taken to ensure 
the water resistant O-ring is properly seated in the O-ring gasket. 
Failure to do so will void the warranty of the camera.
